It certainly seems so from the information you have provided - but on
the other hand, a general problem that rendered 'netstat' unusable
would probably have gained a lot more attention, since 'netstat' isn't
just something that is run in the "daily report", but a very
fundamental tool for examining all kinds of network properties.
Personally I have 3 hosts with 12.1-RELEASE and one with 12-STABLE
post 12.1-RELEASE, and none of them exhibit this problem.

I don't use freebsd-update though, so one possibility might be that it
caused this breakage - but a lot of people do use it, and AFAIK none
of them have reported a problem like this. Additionally, AFAICS there
hasn't been any updates to libnetgraph after 12.1-RELEASE - the last
libnetgraph update on the 12 branch seems to be at svn r348827, while
12.1-RELEASE was at r354233 - i.e. it seems extremely unlikely that a
broken freebsd-update update is the cause.

I.e. it might be a FreeBSD problem, but if so, there is something
specific to your environment that is triggering it...
